Syngenta Announces EPA Registration of Tavium Plus VaporGrip Technology

Syngenta officials say it is the market’s first residual dicamba premix.

Syngenta has announced that Tavium Plus VaporGrip Technology herbicide has been registered by the EPA.

Syngenta officials say it is the market’s first premix residual dicamba herbicide. Tavium, a proprietary Syngenta premix, will be available for the 2019 growing season, subject to state approvals. 
 
Tavium can be used preplant, at planting and early postemergence on Roundup Ready 2 Xtend Soybeans and Bollgard II XtendFlex Cotton. The premix of dicamba and S-metolachlor offers growers a convenient new tool to manage key ALS-, PPO- and glyphosate-resistant broadleaf and grass weeds, say Syngenta officials. 

“Unlike all other stand-alone dicamba products, the multiple effective sites of action in Tavium broaden the activity spectrum and increase its overall efficacy and sustainability,” said Bobby Bachman, herbicide product lead at Syngenta, in a company news release. “The addition of S-metolachlor with dicamba in a premix not only helps manage resistance but also offers up to three weeks longer residual control than dicamba alone.”
 
The Tavium formulation targets driver weeds, including waterhemp, Palmer amaranth, horseweed (marestail), common and giant ragweed, kochia, morningglory, barnyardgrass, and foxtail.
 
Syngenta officials say Tavium will be a tool for growers in the fight against the most difficult-to-control resistant weeds and is formulated for exceptional performance by:

  • Managing emerged weeds through contact activity
  • Controlling weeds that have yet to emerge with residual activity 
  • Providing up to three weeks longer control than dicamba alone
  • Working in all tillage systems and various geographies in both pre- and early postemergence applications

Tavium should be used as part of a two-pass program in order to preserve the efficacy of auxin technologies like dicamba. Syngenta recommends applying Tavium in a two-pass system, following a pre-emergence application of Boundary 6.5 EC, BroadAxe XC or Prefix herbicides in soybeans, or after Caparol 4L herbicide in cotton. 
 
“The premix formulation provides an easy way to reduce selection pressure on dicamba, but a system of pre- and postemergence herbicides is still crucial,” Bachman said. “Practicing sound resistance management principles – such as starting clean and using diversified management and agronomic practices – will help growers be good stewards of the technology.”
